Abstract
The invention is an annuloplasty ring, and associated methods therefore, configured to reshape a native heart valve annulus to correct heart valve function, and also configured to be reshaped into a generally circular form in order to receive and/or support a prosthetic heart valve. The annuloplasty ring may be configured to have a generally D-shaped configuration when initially implanted to correct native valve function, but to assume a generally circular form when subjected to an outward force such as that provided by a dilation balloon.
Claims30
An annuloplasty ring comprising:
- a generally curved portion, wherein the generally curved portion is generally rigid;
- and
- a generally straight portion, wherein the generally straight portion is generally flexible.
An annuloplasty ring comprising:
- a first generally rigid section;
- a second generally rigid section;
- a restraint configured to prevent movement of the first generally rigid section with respect to the second generally rigid section, wherein the restraint is further configured to permit movement of the first generally rigid section with respect to the second generally rigid section when the annuloplasty ring is subjected to a dilation force.
An annuloplasty ring having a generally non-circular shape and comprising a generally rigid portion defining at least a portion of the generally non-circular shape, wherein the annuloplasty ring is configured to assume a generally circular shape when dilated by a balloon catheter.
An annuloplasty ring having a first configuration defining a first orifice area and a second configuration defining a second orifice area, wherein the second orifice area is greater than the first orifice area, wherein the annuloplasty ring is configured to transform from the first configuration to the second configuration when subjected to a dilation force.
A method of repairing a patient's heart function, comprising:
- providing an annuloplasty ring having a first configuration having a first inner area but configured to assume a second configuration having a second inner area when subjected to a dilatational force, wherein the second inner area is greater than the first inner area;
- and
- implanting the annuloplasty ring in a heart valve annulus.
